Product Overview
This Sulfur 10 ppm ICP-ML single-element standard is meticulously formulated for high-precision analytical applications, ensuring accurate calibration in ICP-MS and ICP-OES instrumentation. The liquid form provides uniform distribution and stability, minimizing matrix interference during analysis. Manufactured under stringent quality controls, this standard meets ISO 17034 and NIST traceability requirements, guaranteeing reliability for trace sulfur determination in environmental, pharmaceutical, and industrial samples. The ICP-ML grade ensures ultra-low background contamination, making it suitable for sub-ppb detection limits. Packaged in high-density polyethylene bottles with tamper-evident seals, the solution maintains integrity during storage and handling. Each batch undergoes rigorous multi-point calibration verification, with certificate of analysis provided for lot-specific accuracy data. The 10 ppm concentration offers optimal sensitivity for routine analysis while allowing easy dilution for lower-range applications. Compatible with most inorganic acid matrices, this standard eliminates the need for complex sample preparation, streamlining laboratory workflows.
FAQs
1. What is the shelf life of this Sulfur 10 ppm standard when unopened?
The unopened standard maintains its certified concentration for 24 months from the date of manufacture when stored at 15-25°C in its original packaging.
2. Can this standard be used with organic solvents?
This aqueous-based standard is specifically formulated for inorganic acid matrices and may not be compatible with organic solvents without proper validation.
3. What alternatives exist for higher concentration sulfur standards?
For higher concentrations, consider our 100 ppm or 1000 ppm sulfur standards, which offer similar purity levels with adjusted dilution protocols.
4. How should I prepare dilutions from this 10 ppm standard?
Use Class A volumetric glassware and 2% nitric acid as the diluent, following serial dilution techniques to maintain accuracy at lower concentrations.
5. What documentation accompanies this standard?
Each bottle includes a certificate of analysis with lot-specific data, preparation method, and uncertainty statements for full traceability.
